SEOmoz’s 2011 Search Engine Ranking Factors offers some interesting details about Google’s current algorithm as it relates to individual page features and their correlation to search rank based on 10,000+ pages they tested earlier this year.

The correlation chart below outlines how features on a page tend to relate to higher rankings on a scale from 0 to 1. There are also negative correlations which means the more the particular feature showed up on a page, it tends to relate to lower rankings. But, remember these are correlations, not causes and based on a test of 10,000 pages. So, don’t run off and change your site just because you see something here that correlates to higher or lower rank, but do consider it especially in light of the Panda updates.

Well, now I know the shapes that will be prancing through my nightmares. I’m looking at the list of negatives and realizing I can’t do too much about most of them. Google AdSense pixels are bad?AstroGremlin recently posted..You Don’t Know Your Best Ideas
